  2. Transverse Wave direction of disturbance direction of wave transfer of energy SIMULATION Simulate the effect different degrees of force have on a wave. 15.1 Waves transfer energy. wave medium mechanical wave transverse wave longitudinal wave CHAPTER RESOURCES SECTION OUTLINE

  3. Longitudinal Wave direction of disturbance direction of wave transfer of energy 15.1 Waves transfer energy. wave medium mechanical wave transverse wave longitudinal wave CHAPTER RESOURCES SECTION OUTLINE

  4. Wavelength is the distance from one crest or trough to the next. crest water level at rest fixed point Amplitude is the distance a medium moves above or below its position at rest. trough 15.2 Waves have measurable properties. crest trough amplitude wavelength frequency Frequency is the number of wavelengths passing a fixed point in a certain amount of time. CHAPTER RESOURCES SECTION OUTLINE
